I want to clean up the patchy marks on my forehead.

I am concerned because my forehead skin looks even more patchy these days, especially during the summer. I didn't used to pay much attention to it, but perhaps due to the increased sunlight during the summer, the color on my forehead appears much more uneven. Even with makeup, it isn't completely covered, and it feels like the dullness returns over time.

I am applying sunscreen, but the marks that have already formed do not seem to disappear easily. I am not exactly sure if they are melasma, blemishes, or hyperpigmentation. Therefore, I would like to get a diagnosis from a dermatologist and consult about what kind of care is necessary.

I have heard that when it comes to summer skin concerns, managing pigmentation or blemishes requires careful timing. I am a bit cautious because post-procedure care seems crucial for areas like the forehead that receive a lot of sunlight. If anyone has consulted a dermatologist or received treatment for patchy marks on their forehead, I would like to know what kind of care was helpful. I would also like to know the cost and recovery period.
